Non-refillable bottle.



UNITED STATES PATENT OFFIC WVILLIAM O. LEAK, OF SAN ANTONIO, TEXAS, ASSIGNOR OF ONE-HALF TO OTTO GRAFF AND ALBERT HEAD, OF SAN ANTONIO, TEXAS.

NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 691,553, dated January 21, 1 902.

Application filed April 3, 1901. Serial No. 54,147. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM C. LEAK, a citizen of the United States, and a resident of San Antonio, in the county of Bexar and State of Texas, have invented a new and Improved Non-Refillable Bottle, of which the following is a full, clear, and exact descrip-' tion.

This invention relates to a non-refillable bottle in which the liquid is prevented from being poured back into the bottle by a check which is seated in the lower part of the neck and controlled by a plunger, which when the bottle is turnedinto upright position enables the check to move fromits seat, thus permitting the liquid to run out of the bottle.

This specification is a specific description of two forms of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forminga part of this specification,

in which similar characters of referenceindicate corresponding parts in all the views.

Figure 1 is a sectional view of the invention,showing the bottle in an upright position. Fig. 2 is a sectional view showing the bottle in a horizontal position and illustrating the action of the check. Fig. 3 is a detail view of the check; and Fig. t is a sectional view of the plunger, showing a slight modification thereof.

a indicates the neck of a bottle, which is formed with a cavity a, therein.

1) indicates the plunger, which'is fitted in the neck of the bottle and which is formed with spiral grooves b in its surface, such grooves permitting the liquid to flow past the plunger. The plunger is held to have limited movement within the neck a by means of studs 17 which are located within the cavity at and fastened to the plunger. These studs are formed of some resilient material-for example, cork or rubber-so that when the plunger is to be inserted into the neck the studs b may be pushed or compressed into the plunger, and thus allowed to pass the contracted upper portion of the neck. As soon as the studs reach the cavity a they will expand in the cavity, and thus the plunger will be locked into the neck. The plunger is provided at its lower end'with a projection 6 the purpose of which will be hereinafter specified.

The lower part of the neck of the bottle is formed with a concave seat a, and within this seat is arranged the check 0. is preferably formed of glass, the seating-surface of' which is ground to conform accurately to the surface of the seat a", so that when the check is in position, as in Figs. 1 and 2, it will be impossible for any liquid to pass into the bottle. The check is formed with a cavity in its upper side in which the projection 12 of the plunger I) normally is received.

When the cork is'drawn fromithe bottle,

the bottle upon being inverted will allow the liquid contents to run out. This is due to the fact that both the plunger and the check drop, thus leaving a space within the seat a and permitting the liquid to pass out of the bottle. The instant the bottle is restored.- however, to its upright position the parts I) and 0 will fall back, and it will be impossible to introduce any liquid into the. bottle. Reference to Fig. 2will show that the bottle cannot be filled by laying it flat. In this position most devices of this class fail properly to perform their functions; but with my invention the check 0 lies on its seat when the bottle is laid flat, and the projection 12 lies on the check and tends to hold it in place. This makes the bottle absolutely non-refillable.

The modified form of the invention shown in Fig. 2 relates to the lugs or studs which hold the plunger within the neck of the bottle. Instead of employing the studs 6 as in Figs. 1 and 2, I may employ a lock-bar b which is pivoted within a cavity 19 in the plunger b and which when thrown to the position indicated by dotted lines in Fig. twill permit the plunger to pass into the neck of the bottle, but which when occupying its normal position will lie within the cavity a, of the neck and hold the plunger from movement beyond the same. It will be observed that at its ends this lock-bar forms studs This check which in yieldingly engaging in the cavities at act the sameas the elements I) before described.

Various changes in the form, proportions, and minor details of my invention may be resorted to Without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a bottle having a concave seat in the lower part of its neck and an annularcavity in the neck above the seat, of a concave-convex check adapted to lie in said seat to close the same, the check being movable upward to open, a plunger mounted in the neck above the check, a stud carried on the plunger and lyingin said annular cavity to retain the plunger and allow it a limited movement toward and from the check, and also a sidewise movement, and a projection carried by the plunger and extendinginto the concave portion of the check, for the purpose specified.

2. The combination witha bottle having an annular concavity in the neck thereof, of a check arranged in the neck, a plunger work ing with the check, and laterally-projected studs carried by the plunger and fitting in the concavity in the neck,said studs being formed of resilient material capable of being compressed into the plunger as the plunger is moved into position.

3. lhe combination, with a bottle having a cavity in the neck thereof, of a check arranged in the neck, a plunger working with the check, and a laterally-projected'stud carried by the plunger and fitted in the cavity of the neck, said stud being yieldingly mounted so as to be capable of moving into the plunger as the plunger is passed through the contracted portion of the neck.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM C. LEAK.
